Switching to using a universal code formatter

I’m less familiar with the effects of --skip-string-normalization but almost certainly have less of an objection there.

Basically, black uses " over ’ for quotes. See here, for their explanation.

--skip-string-normalization skips this check, and thus won’t auto format ’ into ".

If you are adopting Black in a large project with pre-existing string conventions (like the popular “single quotes for data, double quotes for human-readable strings”), you can pass --skip-string-normalization on the command line. This is meant as an adoption helper, avoid using this for new projects.
